Both Batch Normalization and Layer Normalization can normalize the input \(x\). What is the difference between them. In this tutorial, we will introduce it.
Batch Normalization Vs Layer Normalization
Batch Normalization and Layer Normalization can normalize the input \(x\) based on mean and variance.

The key difference between Batch Normalization and Layer Normalization is:
How to compute the mean and variance of input \(x\) and use them to normalize \(x\).
As to batch normalization, the mean and variance of input \(x\) are computed on batch axis. We can find the answer in this tutorial:

As to input \(x\), the shape of it is 64*200, the batch is 64.
Batch Normalization can normalize input \(x\) as follows:
However, layer normalization usually normalize input \(x\) on the last axis and use it to normalize recurrent neural networks. For example:

Batch Normalization can normalize input \(x\) as follows:
It means we will compute the mean and variance of input \(x\) based on the row, not column.
